circle in a square

I don't have any idea from where you are getting these questions.But this definitely doesn't look like like a GMAT question for it requires too many steps.I dunno,but even by MGMAT standards,this questions doesn't look like a GMAT Q.

I am also not sure whether the source is a good one because it made a simple error in this question : we say ratio of something to something and not something and something.

Hey goyalsau, these questions are not at all GMAT questions, it is good if you're looking for good geometry practice but such questions require applying theorems and corollary's, which GMAT doesn't test, don't know which source you are using. i'd suggest you don't waste time on such questions. Get to know what areas GMAT covers on geometry, hope you might be knowing already.

I agree with you beat_gmat_09.

Doing such questions is a wastage of time because GMAT tests your IQ and not your knowledge.

Thanks Guys,,,,,,,,,,
